Photography of a striking contrast, featuring a profile silhouette of a man against a vibrant yellow background. Employ a camera setup that mimics the effect of a large aperture, ensuring focus is sharply on the silhouette's edge, while using a low ISO to retain the depth and richness of color with no grain. The image is photorealistic and captured in ultra-high definition, set in a 9:16 aspect ratio. Enhance with a touch of creative flair for an authentic, raw style.
